Cosine is one of the three part for trigonometry. 

You have sin, cos, and tan. 

You can easily do this by understanding SOH CAH TOA. 

Sin = OPPO. over HYPOTENUSE
Cos = ADJACENT over HYPOTENUSE
Tan = OPPO. over ADJACENT 

I hope this helps!

The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2
Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = \frac{k}{P} ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = \frac{k}{20} ( multiply both sides by 20 )

k = 7200

V = \frac{7200}{P} ← equation of variation

When V = 480, then

480 = \frac{7200}{P} ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15

Joe purchased 15 pairs of socks from an online vendor and received a 20% discount. shipping cost $4.99. how much does each pair
cluponka [151]

Take the total: $79.99

Subtract the shipping cost: $4.99 ($75)

Divide that by the number of socks: 75/15
=$5 per sock with the discount

Take the discount of 20% and multiply that by the sock price $5 - 5 x .20 = 1

Add that to the sock price: 1 + 5 = 6

$6 per sock without the discount is your answer
